Description

양극형 전기 소작 팁이 포함된 스텐트 전달 시스템Stent delivery system with bipolar electrocauterization tip
본 발명은 스텐트 전달 시스템에 관한 것이다. The present invention relates to a stent delivery system.
스텐트(stent)는 인체 내의 막힌 곳에 삽입하여 혈액, 체액, 음식물, 체내노폐물 등의 순환 경로를 확보하는데 사용되는 관내인공삽입물(endoprostheses) 디바이스이다. A stent is an endoprostheses device that is inserted into a blockage in the human body and used to secure a circulation path of blood, body fluids, food, and body wastes.
이러한 스텐트는 플라스틱 재질 또는 금속 재질이 주로 사용되고 있다. 먼저 플라스틱 재질의 경우 직경이 가늘어 쉽게 삽입할 수 있는 반면, 재질적 특성 및 가는 직경 때문에 자가확장이 붕괴되며 다시 스텐트 시술부위가 막하는 문제가 있다. The stent is mainly used plastic or metal material. First, in the case of a plastic material, the diameter is thin, so that it can be easily inserted. However, due to the material properties and the thin diameter, the self-expansion is collapsed and the stent site is blocked.
그래서 의료분야에서는 금속재질의 스텐트를 많이 사용하고 있다. 금속 재질의 경우 값은 비싸지만, 기본적으로 내재된 강성이 있어 스텐트 시술부위 신체 조직에서 간헐적 근육수축, 인가되는 외부 충격 등이 발생하더라도 일시적으로 수축되지만 다시 자가확장되므로, 그 기능을 유지함에 있어서 효율적인 측면이 있다.Therefore, the medical field is using a lot of metal stents. In the case of metal materials, the price is expensive, but the inherent rigidity is basically so that even if intermittent muscle contraction or applied external shock occurs in the body tissue of the stent, it contracts temporarily, but expands itself again. There is a side.
최근에는 혈관, 요관, 담관 등의 인체의 순환경로상에 폐색, 손상 등의 문제가 발생했을 때에, 예전처럼 외과적인 수술방법이 사용되기 보다는, 비수술적 방법이 선호되고 있으며, 그 일환으로서 스텐트 시술이 활성화되고 있는 추세이다.Recently, when a problem such as occlusion or damage occurs in the human circulation such as blood vessels, ureters and bile ducts, non-surgical methods are preferred rather than the conventional surgical methods, and as a part, stent surgery This is a trend that is being activated.
이러한 스텐트를 시술하고자 하는 신체 조직 부위로 삽입하기 위해 카테터(catheter)와 같은 스텐트 전달 시스템(stent delivery system)이 사용되고 있다. A stent delivery system such as a catheter is used to insert the stent into the body tissue to be treated.
여기서 스텐트 전달 시스템을 간략히 살펴보면, 기본적으로 전기 소작 팁, 삽입용 튜브, 스텐트, 손잡이, 전류커넥터 등을 포함하여 구성된다. Here is a brief look at the stent delivery system, which basically includes an electrical cauterization tip, insertion tube, stent, handle, current connector, and the like.
전류커넥터는 전기 시술기와 같은 외부 전류원과 연결되어 가열용 전류를 공급받는 부속이며, 전기 소작 팁은 이러한 전류커넥터와 도선으로 연결되어 전류를 전달받아 신체 조직을 소작하여 구멍을 형성하는 기능을 수행하는 부속이다. The current connector is a part that is connected to an external current source such as an electric surgery machine to receive a heating current, and the electrical cauterization tip is connected to the current connector and a conductor to receive current to cauterize body tissue to form a hole. It is a part.
그리고 통상 삽입용튜브는 절연재질로 구성되고, 삽입용튜브 내부에는 스텐트가 내장되어 있어, 시술자가 손잡이의 조작을 통해 삽입용튜브를 소작구멍을 통해 신체 조직에 삽입하고 시술하고자 하는 부위에 스텐트를 위치시키게 된다.And usually the insertion tube is made of an insulating material, the stent is built in the insertion tube inside, the operator inserts the insertion tube into the body tissue through the cautery hole through the operation of the handle and the stent is placed on the site to be treated It is located.
이후 손잡이 조작을 통해 삽입용튜브에서 스텐트가 노출되도록 하고, 스텐트가 자가확장되며 시술 부위의 폐색, 손상 등을 해결하게 된다. After the handle operation to expose the stent in the insertion tube, the stent is self-expanded, and to solve the blockage, damage, etc. of the treatment site.
도 1를 참고하면, 종래 다수의 스텐트 전달 시스템(10)에 사용되는 전기 소작 팁(13)은 단극만이 배치되는 경우가 많다. 도 1에 도시된 내용은 단극형 전기 소작 팁(13)이 구비된 회로 시스템을 나타낸 것이고, 이는 단극형 전기 소작 팁(13)의 작동원리 설명을 위해 인용한 것이다.Referring to FIG. 1, the electrocauterization tip 13 used in a number of conventional stent delivery systems 10 is often arranged with only a single pole. 1 shows a circuit system with a monopolar electrocauterization tip 13, which is cited for explanation of the principle of operation of the monopolar electrocauterization tip 13.
이 경우 시술방식은 시술자가 외부 전류원(11)의 일극에 전선(12)를 이용하여 전기 소작 팁(13)과 연결하고, 환자(H)의 신체 일부에 다른 극이 전도될 수 있도록 전극패치(14)를 배치한다. 그리고 전극패치(14)를 전선(15)를 이용하여 외부 전류원(11)의 다른 극에 연결한다. In this case, the procedure is performed by the operator using an electric wire 12 to one pole of the external current source 11 and the electrical cauterization tip 13, and the electrode patch (so that the other pole can be conducted to a part of the body of the patient H). 14). The electrode patch 14 is connected to the other pole of the external current source 11 using the wire 15.
시술자가 외부 전류원(11)의 전원을 켜고 전류 크기를 조절하며 신체 조직을 소작하게 된다. 전류는 도 1에 게시된 화살표 방향과 같이 흐르고(혹은 반대 방향) 전기 소작 팁(13)의 끝단부에서는 신체 내부를 흘러 전극패치(14) 방향으로 흐르게 된다. The operator turns on the external current source 11, adjusts the current magnitude, and cauterizes the body tissue. The current flows in the direction of the arrow shown in FIG. 1 (or in the opposite direction) and flows in the body toward the electrode patch 14 at the end of the electrocauterization tip 13.
이때 전류는 체내를 흐르게 되므로, 자칫 실수가 발생되면, 환자에게 전기적 충격을 주거나 심한 경우 조직화상, 조직괴사 등의 신체 손상을 입히는 문제가 발생한다. At this time, since the current flows through the body, when a mistake occurs, a problem occurs that causes an electric shock to the patient or, in severe cases, damages such as tissue burns and tissue necrosis.
이를 완화하기 위해서는 전기 소작 팁(13)과 전극 패치(14)간의 거리를 최대한 가깝게 하는 것이 좋으나, 스텐트를 시술하고자 하는 신체 부위의 위치에 따라 물리적인 제한이 있다. In order to alleviate this, it is preferable to keep the distance between the electrocauterization tip 13 and the electrode patch 14 as close as possible, but there are physical limitations depending on the position of the body part to be treated with the stent.
따라서 환자에 대한 시술 안정성을 보다 확보할 수 있는 구조가 요구되는 실정이다. Therefore, there is a need for a structure that can more secure the surgical stability of the patient.
또 다른 문제점으로 종래의 스텐트 전달 시스템은 삽입용튜브가 절연재질로 되어 있어, 의사, 간호사와 같은 시술자가 잘못 사용하여 충격을 가하는 경우 쉽게 구부러지거나 꺾이는 현상이 발생된다. 심한 경우 외부 손상으로 인해 끊어지는 문제가 발생하기도 한다.Another problem with the conventional stent delivery system is that the insertion tube is made of an insulating material, such that a surgeon easily bends or bends when a surgeon, such as a doctor or a nurse, incorrectly applies an impact. In severe cases, external damage may cause the problem.
만약 이러한 문제가 실제 시술과정에서 발생된다면, 환자와 같은 시술대상자에게는 치명적인 의료사고로 이어질 수 있다. If this problem occurs during the actual procedure, it can lead to fatal medical accidents for the subject such as the patient.
삽입용튜브는 인체 내부로 삽입되는 것이므로, 어느 정도의 유연성은 보장되어야 하며, 또한 인체에 닿는 부속이므로 전기적으로 절연성이 유지되어야 한다. 따라서 스텐스 시술 기술분야에서는 상기와 같은 삽입용튜브의 기본적인 특성을 유지하면서도, 의사, 간호사와 같은 시술자의 부주위에도 쉽게 손상되지 않도록 내구성이 향상된 튜브가 요구되고 있다. 물론 전기 소작 팁까지 연결되는 도선의 배치 또한 적절히 고려되어야 할 수 있어야 한다.Since the insertion tube is inserted into the human body, a certain degree of flexibility should be ensured, and since it is an accessory touching the human body, it must be electrically insulated. Therefore, in the technical field of the stent treatment, while maintaining the basic characteristics of the insertion tube as described above, there is a demand for improved tube durability so as not to be easily damaged by the sub-circumference of the operator, such as doctors, nurses. Of course, the arrangement of the leads leading to the electrocauterization tip also needs to be considered properly.
또한 현재 사용되는 대부분의 스텐트 전달 시스템은 전기 소작 팁의 크기가 고정되어 있어서, 시술대상자의 신체 조직내 시술환경에 따라 소작 구멍의 크기를 조절할 수 없는 문제가 있다. 이는 가변적인 시술환경 변화에 적절히 대응할 수 없는 한계를 야기한다.In addition, most of the currently used stent delivery system is fixed in the size of the electrocauterization tip, there is a problem that can not adjust the size of the cauterization hole according to the treatment environment in the body tissue of the subject. This leads to limitations that cannot adequately respond to variable treatment environment changes.
따라서 보다 향상된 시술환경을 조성하기 위해, 신체 조직의 시술 부위에서 요구되는 다양한 형태의 스텐트를 전달하기 위한, 신체 조직에 소작 구멍을 가변적으로 조절할 수 있는 시술장치가 요구되는 실정이다.Therefore, in order to create an improved treatment environment, a situation that requires a surgical device that can variably adjust the cautery hole in the body tissue to deliver the stent of various forms required in the treatment site of the body tissue.

양극형 전기 소작 팁(23)의 경우 외부 전류원(21)에 도선(22)을 이용하여 전기 소작 팁 중 어느 하나의 전극체에 연결하고, 또한 다른 하나의 전극체도 도선(25)를 이용하여 외부 전류원(21)과 연결한다. In the case of the bipolar electrocauterization tip 23, an external current source 21 is connected to an electrode body of any one of the electrocauterization tips using a conductor 22, and the other electrode body is also externally connected using a conductor 25. It is connected to the current source 21.
이후 시술자가 전류값을 결정하고 시술하게 되면, 양극형 전기 소작 팁(23)의 전극체간에 곧바로 전류가 전도되어 흐르며 신체 조직의 소작 작업을 수행하게 된다. Then, when the operator determines the current value and performs the procedure, current is directly conducted and flows between the electrode bodies of the bipolar electrocauterization tip 23 to perform cauterization of body tissues.
이에 따라 체내에서의 전류 흐름 거리는 최소화가 되므로, 단극을 사용하는 전기 소작 팁에 비해 신체에 전기적 충격을 주거나 조직화상, 조직괴사 등의 부작용을 완화할 수 있게 된다. Accordingly, since the current flow distance in the body is minimized, compared to the electrocauterization tip using a single pole, it is possible to alleviate side effects such as electric shock, tissue burn, and tissue necrosis.

이때 상기 제1 전극선(123) 및 제2 전극선(125)은 전도성 금속재질로 구현될 수 있으며, 이러한 상기 제1 전극선(123) 및 제2 전극선(125)이 복수회로 감기면서 제1 내부튜브(410)에 배치됨에 따라 제1 내부튜브(410)의 강성은 향상되게 된다. In this case, the first electrode line 123 and the second electrode line 125 may be formed of a conductive metal material, and the first electrode tube 123 and the second electrode line 125 may be wound in a plurality of circuits, and thus, the first inner tube ( As the 410 is disposed, the rigidity of the first inner tube 410 is improved.
바람직하게는 제1 내부튜브(410)의 내부 중앙측에는 인너홀(411)이 형성되고, 이를 위해서 제1 내부튜브(410)는 일정한 두께를 가진다. 상기 제1 전극선(123) 및 제2 전극선(125)은 개별 절연되어 이러한 두께 부분에 배치되고, 이에 따라 상기 제1 전극선(123) 및 제2 전극선(125)은 전체적으로 절연코팅제에 의해 둘러 쌓여 제1 내부튜브(410)의 둘레를 따라 나선 방향으로 복수회 감기며 배치되게 된다.Preferably, an inner hole 411 is formed at an inner central side of the first inner tube 410, and for this purpose, the first inner tube 410 has a predetermined thickness. The first electrode line 123 and the second electrode line 125 are separately insulated and disposed in the thickness portion, and thus the first electrode line 123 and the second electrode line 125 are entirely surrounded by an insulating coating agent. 1 It is disposed while winding a plurality of times in a spiral direction along the circumference of the inner tube (410).
각각의 제1 전극선(123) 및 제2 전극선(125)은 개별적으로 코팅되어 있으므로, 합선의 가능성은 낮아지게 된다. 이로 인한 제1 내부튜브(410)의 열화손상은 방지할 수 있다. Since each of the first electrode lines 123 and the second electrode lines 125 is coated separately, the possibility of a short circuit becomes low. As a result, deterioration of the first inner tube 410 may be prevented.
다음 도 13를 참고하면, 상기 제1 내부튜브(410)의 또 다른 형태가 게시된다. 본 형태에서는 상기 제1 내부튜브(410)는 절연코팅제로 제공되고, 상기 제1 전극선(123) 및 제2 전극선(125)은 개별 절연코팅된다. 그리고 상기 제1 내부튜브(410)와 일체로 다시 한번 코팅되며, 상기 제1 내부튜브(410)의 둘레를 따라 직조 형태의 전극선(120c)으로 배치된다. Referring next to FIG. 13, another form of the first inner tube 410 is posted. In this embodiment, the first inner tube 410 is provided with an insulating coating agent, and the first electrode line 123 and the second electrode line 125 are individually insulating coated. The coating is once again integrally formed with the first inner tube 410, and disposed as a woven electrode line 120c along the circumference of the first inner tube 410.
이때 전극선(120c)은 금속재질로 구현될 수 있으며, 이러한 전극선(120c)이 직조형태로 반복적으로 제1 내부튜브(410)에 배치됨에 따라 제1 내부튜브(410)의 강성은 향상되게 된다. In this case, the electrode line 120c may be implemented with a metal material, and the rigidity of the first inner tube 410 is improved as the electrode line 120c is repeatedly disposed in the first inner tube 410 in a woven form.
정확하게는 제1 내부튜브(410)의 내부 중앙측에는 인너홀(411)이 형성되고, 이를 위해서 제1 내부튜브(410)는 일정한 두께를 가진다. 상기 제1 전극선(123) 및 제2 전극선(125)은 이러한 두께 부분에 배치되고, 이에 따라 전극선(120c)은 전체적으로 절연코팅제에 의해 둘러 쌓여 제1 내부튜브(410)의 둘레를 따라 반복적인 직조 형태로 배치되게 된다. In detail, an inner hole 411 is formed at an inner central side of the first inner tube 410, and for this purpose, the first inner tube 410 has a predetermined thickness. The first electrode wire 123 and the second electrode wire 125 are disposed in such a thickness portion, and thus the electrode wire 120c is entirely surrounded by an insulating coating agent to be woven repeatedly along the circumference of the first inner tube 410. It will be arranged in the form.
물론 개별 절연코팅되어 있으므로, 상기 제1 전극선(123) 및 제2 전극선(125)간에 합선은 차단할 수 있다. Of course, since the individual insulation coating, the short circuit between the first electrode line 123 and the second electrode line 125 can be blocked.
이렇듯 본 발명은 제1 내부튜브(410) 내에서는 나선형태의 전극선(120b), 직조형태의 전극선(120c)의 구조를 통해 전류 전도뿐만 아니라, 제1 내부튜브(410)의 강성을 강화할 수 있는 부가적인 효과를 발휘할 수 있다. 물론 나선형태, 직조형태에 한정될 것은 아니고, 강성 강화를 위한 다른 구조도 가능할 것이다. As such, the present invention can strengthen the rigidity of the first inner tube 410 as well as conducting current through the structure of the spiral electrode line 120b and the woven electrode line 120c in the first inner tube 410. Additional effects can be exerted. Of course, it is not limited to the helical, woven form, other structures for stiffening will be possible.
다음으로 상기 제2 내부튜브(430)는 도 11 및 도 15를 참고하면, 상기 제1 내부튜브(410)의 외측 둘레 일부를 감싸며 배치되고, 상기 제1 내부튜브(410)와 연계되어 일체로 이동되도록 제공될 수 있다. 이러한 제2 내부튜브(430)는 절연물질로 구현될 수 있다. Next, referring to FIGS. 11 and 15, the second inner tube 430 is disposed to surround a portion of the outer circumference of the first inner tube 410, and is integrally connected with the first inner tube 410. It may be provided to be moved. The second inner tube 430 may be implemented with an insulating material.
도 15를 참고하면, 제2 내부튜브(430)는 상기 제1 내부튜브(410)의 외측 둘레 일부를 감싸며 배치되고, 이때 스텐트(150)를 미는 사인블록(433)이 제2 내부튜브(430)의 단부에 배치된 것을 확인할 수 있다. Referring to FIG. 15, the second inner tube 430 is disposed to surround a part of the outer circumference of the first inner tube 410, and a sine block 433 pushing the stent 150 includes the second inner tube 430. It can be seen that it is disposed at the end of the).
그리고 도 11를 참고하면, 상기 제2 내부튜브(430)는 외부튜브(450)의 내부에 배치되면서, 상기 이동바(490)의 튜브연결부(492)의 외측 둘레에 끼워지며 연결된 모습을 확인할 수 있으며, 그 내부에 배치된 제1 내부튜브(410)는 이동바(490)의 튜브연결부(492)의 관통홀에 끼워져 연결된 상태를 확인할 수 있다. And, referring to Figure 11, the second inner tube 430 is disposed inside the outer tube 450, it can be seen connected to the outer circumference of the tube connection portion 492 of the moving bar 490 is connected. The first inner tube 410 disposed therein may be connected to the through hole of the tube connection portion 492 of the moving bar 490 to be connected thereto.
이에 따라 시술자가 이동바(490)를 이동시키면, 이동바(490)와 연결된 제1 내부튜브(410) 및 제2 내부튜브(430)가 일체로 이동바(490)의 이동방향으로 함께 이동하게 된다.Accordingly, when the operator moves the moving bar 490, the first inner tube 410 and the second inner tube 430 connected to the moving bar 490 move together in the moving direction of the moving bar 490. do.
다음 상기 외부튜브(450)는 도 11 및 도 15를 상기 제2 내부튜브(430)를 감싸며 배치되고 제1 손잡이부(470)의 단부에 연결 고정되는 부분일 수 있다. 즉 외부튜브(450)는 제1 손잡이부(470)에 고정되기 때문에 이동바(490)의 이동에 따라 이동하지는 않으며, 다만 제1 내부튜브(410) 및 제2 내부튜브(430)의 이동을 안내하고 지지하는 기능을 하게 된다. 이러한 외부튜브(450)는 절연물질로 구현될 수 있다. Next, the outer tube 450 may be a portion that is arranged surrounding the second inner tube 430 and connected to the end of the first handle 470 in FIGS. 11 and 15. That is, since the outer tube 450 is fixed to the first handle part 470, the outer tube 450 does not move according to the movement of the movement bar 490, but moves the first inner tube 410 and the second inner tube 430. It will serve as a guide and support. The outer tube 450 may be implemented with an insulating material.
도 15를 참고하면, 제1 내부튜브(410)와 외부튜브(450)가 형성하는 스텐트공간부(130)에 스텐트(150)가 확장되지 않은 상태로 배치된 것을 볼 수 있다. 즉 제1 내부튜브(410) 중 제2 내부튜브(430)에 의해 감싸여 지지 않은 부분의 둘레를 따라 스텐트(150)가 배치되고, 외부튜브(450)의 내주면에 닿아 있으면서, 스텐트(150)는 확장되지 않은 상태를 유지한다. Referring to FIG. 15, it can be seen that the stent 150 is not extended in the stent space 130 formed by the first inner tube 410 and the outer tube 450. That is, the stent 150 is disposed along the circumference of the portion of the first inner tube 410 not wrapped by the second inner tube 430, and the stent 150 contacts the inner circumferential surface of the outer tube 450. Remains unexpanded.
이때 제1 내부튜브(410)의 외주면에는 스텐트 지지블록(131)이 배치될 수 있다. At this time, the stent support block 131 may be disposed on the outer circumferential surface of the first inner tube 410.
다음 도 11를 참고하면, 상기 제1 손잡이부(470)는 상기 외부튜브(450)의 단부에 연결되는 부분이며, 시술자가 이동바(490)를 이동시키기 위해 잡도록 제공되는 부분일 수 있다. Next, referring to FIG. 11, the first handle part 470 may be a part connected to an end of the outer tube 450, and may be a part provided to be held by the operator to move the movement bar 490.
상기 제1 손잡이부(470)의 일측부에는 고정핸들(473)이 배치될 수 있다. 시술자가 이동바(490)를 이동시킨 후 이동바(490)의 움직임을 제한하고자 한다면, 시술자는 고정핸들(473)을 일방향으로 돌리면 된다. 도면으로 도시하지는 않았으나, 고정핸들(473)을 일방향으로 돌리면, 이동바(490)를 압박하여 이동바(490)의 이동을 제한하게 된다. 반대로 다시 이동바(490)를 이동시키고자 한다면, 시술자는 고정핸들(473)을 반대방향으로 돌려 이동바(490)에 대한 압박을 느슨하게 하면 된다. A fixing handle 473 may be disposed at one side of the first handle 470. If the operator wants to limit the movement of the moving bar 490 after moving the moving bar 490, the operator may turn the fixing handle 473 in one direction. Although not shown in the drawings, when the fixing handle 473 is turned in one direction, the movement of the movement bar 490 is limited by pressing the movement bar 490. On the contrary, if the moving bar 490 is to be moved again, the operator may loosen the pressure on the moving bar 490 by turning the fixing handle 473 in the opposite direction.
이러한 고정핸들(473)은 스텐트(150)가 확장되어야 하는 신체 조직 부위에 인접했을 때에, 스텐트(150)를 정확한 신체 조직 부위에 위치되도록 하기 위해 제공된다. 만약 시술 중 이동바(490)가 움직여 버리면, 스텐트(150)의 위치가 부정확하게 배치될 수 있기 때문이다. This fixation handle 473 is provided to position the stent 150 at the correct body tissue site when the stent 150 is adjacent to the body tissue site to be expanded. If the movement bar 490 moves during the procedure, the position of the stent 150 may be incorrectly disposed.
한편, 도 14를 참고하면, 본 발명에서는 이동바(490)를 고정시키는 다른 형태가 제시된다. 상기 전달부(400)는 이동바(490)를 따라 이동하는 제1 그립바디(471)의 이동을 단계적으로 조절하는 이동조절유닛(475)을 더 포함하여 구성될 수 있다. 반대로 이는 제1 그립바디(471)와의 관계에서 이동바(490)의 이동을 단계적으로 조절하는 것일 수 있다. Meanwhile, referring to FIG. 14, another form of fixing the moving bar 490 is provided in the present invention. The transmission unit 400 may further include a movement control unit 475 for stepwise adjusting the movement of the first grip body 471 moving along the movement bar 490. On the contrary, this may be to gradually adjust the movement of the movement bar 490 in relation to the first grip body 471.
이러한 상기 이동조절유닛(475)은 요철부(476) 및 고정부(477)를 포함하여 구성될 수 있다. 먼저 요철부(476)는 상기 이동바(490)의 길이방향을 따라 절곡형상이 복수회에 걸쳐 형성될 수 있다. 그리고 상기 고정부(477)는 상기 요철부(476)에 결합되면서 이동바(490)를 따라 이동하는 제1 그립바디(471)의 이동을 단계적으로 고정하도록, 상기 제1 손잡이부(470)의 내부에 배치될 수 있다. The movement control unit 475 may be configured to include an uneven portion 476 and the fixing portion 477. First, the uneven portion 476 may be formed a plurality of times bent along the longitudinal direction of the moving bar 490. In addition, the fixing part 477 is coupled to the uneven part 476 to gradually fix the movement of the first grip body 471 moving along the moving bar 490. It can be placed inside.
이러한 고정부(477)는 세부적으로 다시 탄성체(478) 및 고정블록(479)을 포함하여 구성될 수 있다. 상기 탄성체(478)는 상기 제1 손잡이부(470)의 내부에 형성된 내부공간(471a)상에 배치될 수 있다. 이러한 탄성체(478)는 코일 스프링, 판 스프링 등의 형태일 수 있으나, 탄성력을 제공할 수 있다면, 반드시 이에 한정될 것은 아니다. The fixing part 477 may be configured to include the elastic body 478 and the fixing block 479 again in detail. The elastic body 478 may be disposed on an inner space 471a formed in the first handle part 470. The elastic body 478 may be in the form of a coil spring, a leaf spring, or the like, but is not limited thereto if it can provide an elastic force.
그리고 상기 고정블록(479)은 일측은 상기 탄성체(478)에 밀접하고, 타측은 상기 제1 인너홀(472)로 돌출되는 형태로 구현될 수 있다. 이때 시술자가 이동바(490)를 당기거나 밀 때, 상기 요철부(476)의 절곡 형상을 비교적 용이하게 넘어갈 수 있도록, 상기 고정블록(479)상에는 구름휠(479a)에 배치될 수 있다. In addition, the fixing block 479 may be implemented such that one side thereof is close to the elastic body 478 and the other side thereof protrudes into the first inner hole 472. In this case, when the operator pulls or pushes the moving bar 490, the rolling wheel 490 may be disposed on the rolling wheel 479a on the fixing block 479 so that the bending shape of the uneven portion 476 can be easily crossed.
상기와 같은 구조를 통한 이동바(490)의 단계적 이동은, 실제 시술자가 스텐트 시술시 신체 조직의 시술부위에서 스텐트의 안정적인 단계적 자가 확장을 가능하게 한다. Stepwise movement of the moving bar 490 through the structure as described above, the actual operator enables a stable step self-expansion of the stent at the surgical site of the body tissue during the stent procedure.
시술환경, 시술자의 숙련도 등에 따라 스텐트 시술의 완성도는 달라질 수 있다. 만약 시술자가 미숙하여 이동바(490)를 무리하게 당기거나 또는 당기는 과정에서 이동바(490)가 흔들려, 그 진동이 스텐트까지 전달되어 스텐트의 자가 확장이 원활하지 않을 수 있다. The completeness of the stent procedure may vary depending on the treatment environment and the skill of the operator. If the operator is immature, the moving bar 490 is forcibly pulled or the moving bar 490 is shaken during the pulling process, and the vibration is transmitted to the stent, and thus self-expansion of the stent may not be smooth.
이때 이동바(490)가 단계적으로 이동되며 고정될 수 있다면, 이동바(490)를 당김에 따라 외부튜브(450)가 이동하는 것도 단계적으로 명확히 조절이 가능하게 되므로, 스텐트가 노출되는 것도 천천히 단계적으로 진행되게 된다. 이는 스텐트의 정확한 자가 확장을 유도하게 되고, 시술효과도 향상되게 된다. 시술자의 부주의도 조금은 더 완화시키거나 방지할 수도 있다. At this time, if the moving bar 490 is moved in stages and can be fixed, it is also possible to clearly control step by step by moving the outer tube 450 by pulling the moving bar 490, the stent is also exposed slowly step by step Will be proceeded to. This leads to accurate self-expansion of the stent, and the treatment effect is also improved. The carelessness of the operator may be alleviated or prevented even more.
다음으로 도 15 및 도 16을 참고하면, 상기 전기 소작 팁(300)의 측단면도가 게시되어 있다. Referring next to FIGS. 15 and 16, a cross-sectional side view of the electrical cauterization tip 300 is posted.
상기 팁절연부재(320)는 중앙측에 가이드와이어(140)가 삽입 배치되는 팁가이드홀(321)이 형성되어 있다. 그리고 상기 팁절연부재(320)의 양면에는 제1 전극체(313) 및 제2 전극체(315)가 배치되며, 각각 제1 전극선(123) 및 제2 전극선(125)와 용접접합되어 연결되어 있다. 물론 매듭방식도 가능하다. The tip insulating member 320 has a tip guide hole 321 is inserted into the guide wire 140 is inserted in the center side. The first electrode body 313 and the second electrode body 315 are disposed on both surfaces of the tip insulating member 320, and are welded and connected to the first electrode line 123 and the second electrode line 125, respectively. have. Of course, knotting is also possible.
또한 전극체(310)의 외주면 일부에는 외부절연체(380)에 의해 몰딩방식으로 절연코팅될 수 있다. 이는 신체 부위에서 소작하고자 하는 조직 이외의 부위로 전류가 흐르는 것을 방지하기 위함이다. In addition, a portion of the outer circumferential surface of the electrode body 310 may be insulated coated by a molding method by an external insulator 380. This is to prevent current from flowing from the body part to a part other than the tissue to be cauterized.
상기 전극체(310)는 전체적으로 원형 단면 형상일 수 있으며, 상기 전극체(310)는 전류가 인가되어 신체 조직에 열을 가하여 구멍을 내는 부분으로서 금속재질 등의 전도성 물질일 수 있다. 예를 들어 stainless, Ni+Ti alloy 등의 금속 재질일 수 있다. The electrode body 310 may have a circular cross-sectional shape as a whole, and the electrode body 310 may be a conductive material such as a metal material as a current is applied to heat a body tissue to form a hole. For example, it may be a metal material such as stainless or Ni + Ti alloy.
그리고 본 발명의 실시예에서는 상기 외부절연체(380)의 끝단부(380a)는 테이퍼진 형태로 몰딩될 수 있으며, 이러한 구조는 신체 조직에서 스텐트(150) 전달 후 전기 소작 팁(300)를 다시 뺄 때, 제거작업을 비교적 수월하게 하는데 도움을 준다. In the embodiment of the present invention, the end portion 380a of the outer insulator 380 may be molded in a tapered shape, and the structure may be pulled back from the electrical cauterization tip 300 after transferring the stent 150 from body tissue. This helps to make the removal relatively easy.
즉 외부절연체(380)의 일부는 제1,2 전극체(313,315)의 일측부와 반대방향으로 테이퍼진 형상으로 구현될 수 있으며, 이는 전기 소작 팁(300)를 신체에서 뺄 때, 보다 매끄럽게 빠져나올 수 있도록 하는 것이다.That is, a part of the external insulator 380 may be implemented in a tapered shape in a direction opposite to one side of the first and second electrode bodies 313 and 315, which is more smoothly pulled out when the electrical cauterization tip 300 is removed from the body. To make it come out.
신체 조직은 주로 단백질로 되어 있어, 전기 소작 팁(300)에 의해 소작 구멍이 형성되더라도, 신체 조직의 유연성으로 인해 소작 구멍이 좁아지는 성질이 있다. Body tissue is mainly made of protein, even if the cauterization hole is formed by the electrical cauterization tip 300, due to the flexibility of the body tissue has a property that the cauterization hole is narrowed.
이 때 외부절연체(380)가 전극체(310)와 반대방향으로 테이퍼져 있으면, 시술자가 전기 소작 팁(300)을 소작 구멍을 통해 뺄 때, 소작 구멍이 테이퍼진 형상을 타고 벌어지면서 넓어지므로, 전기 소작 팁(300)이 용이하게 빠지게 된다. At this time, if the external insulator 380 is tapered in the opposite direction to the electrode body 310, when the operator removes the electrical cauterization tip 300 through the cauterization hole, the cauterization hole widens as it opens in a tapered shape, The electrocauterization tip 300 is easily pulled out.
이 경우 상기 제1 내부튜브(410)는 외부절연체(380)의 내부로 삽입되며 전극체(310)에 접착되게 된다.In this case, the first inner tube 410 is inserted into the outer insulator 380 and adhered to the electrode body 310.
물론 외부절연체(380)이 반드시 상기 형태들에 한정될 것은 아니다.Of course, the external insulator 380 is not necessarily limited to the above forms.

이러한 나사산은 전극체(310)뿐만 아니라, 팁절연부재(320)상에도 동일하게 가공될 수 있다. These threads may be processed on the tip insulating member 320 as well as the electrode body 310.
도 19 및 도 20에서와 같이, 상기 가변링(350)은 상기 전극체(310)의 직경을 가변토록, 상기 결합부(330)에 연결되는 부분일 수 있다. 상기 가변링(350)은 원형 링 형태일 수 있으며, 내주면에는 상기 결합부(330)의 나사산에 대응되는 나사산이 가공될 수 있으며, 역시 부드럽게 라운딩 가공처리되어 제공될 수 있다. 19 and 20, the variable ring 350 may be a portion connected to the coupling part 330 to vary the diameter of the electrode body 310.

The first ring portion 351 of the variable ring 350 also functions to puncture body tissue.
그리고 양극형 전기 소작 팁(300)의 특성을 발휘하기 위해 상기 가변링(350)의 제2 링부(353)는 팁절연부재(320)과 동일하게 절연재질로 구현될 수 있다. In addition, the second ring part 353 of the variable ring 350 may be formed of an insulating material in the same manner as the tip insulating member 320 in order to exhibit the characteristics of the anode type cauterization tip 300.
이러한 가변링(350)의 일 예로는 도 18 및 도 19에 도시된 것과 같이, 가변링(350)의 외주면이 라운딩된 형태일 수 있다. 이 경우 신체 조직에 열을 가하여 구멍을 내고 전극체(310)가 신체 조직의 내부로 들어가거나 또는 스텐트(150) 시술 후 빠져나올 때, 라운딩 외주면 처리로 인하여 신체 조직에 손상을 주지 않고 보다 부드럽게 들어가거나 또는 빠져나올 수 있다. 물론 전극체(310)와 밀착되어 전기적으로 연결되어 있으므로, 신체 조직에 구멍을 내는 직경 범위 조절도 가능하게 된다. As an example of the variable ring 350, as shown in FIGS. 18 and 19, the outer circumferential surface of the variable ring 350 may be rounded. In this case, when heat is applied to the body tissue to make a hole and the electrode body 310 enters the inside of the body tissue or exits after the stent 150, the rounding outer peripheral surface treatment does not damage the body tissue more smoothly. Or exit. Of course, since it is in close contact with the electrode body 310 and electrically connected, it is possible to adjust the diameter range to puncture the body tissue.
예를 들어 시술자가 신체 조직에 구멍을 내고 싶은 크기를 줄이고 싶으면, 가변링(350)을 분리한 상태에서 전극체(310)를 사용하면 되고, 반대로 스텐트(150)를 전달하고자 하는 신체 조직의 부위에 약간은 더 큰 구멍을 내고자 한다면, 가변링(350)을 끼운 상태에서 전극체(310)를 사용하면 된다. For example, if the operator wants to reduce the size to puncture the body tissue, the electrode body 310 may be used while the variable ring 350 is separated, and the part of the body tissue to which the stent 150 is to be delivered is reversed. If you want to make a slightly larger hole in the, the electrode body 310 may be used while the variable ring 350 is fitted.
본 발명의 실시예에서는 하나의 라운딩 처리된 가변링(350)만을 제시하고 있으나, 가변링(350)상에 라운딩 처리되는 형상은 보다 다양할 수 있으며, 본 발명으로부터 유추될 수 있는 범위내라면 다른 형상도 당연히 포함될 수 있다. In the exemplary embodiment of the present invention, only one rounded variable ring 350 is provided, but the rounded shape on the variable ring 350 may be more diverse, and other ranges may be inferred from the present invention. Shapes can of course also be included.
또한 이러한 가변링(350)의 다른 예로는 도 20에 도시된 것과 같이, 가변링(350)의 외주면이 테이퍼진 형태로 구현될 수 있다. 이때 가변링(350)의 외주면 중 일측은 상기 전극체(310)와 동일한 방향으로 테이퍼진 형상으로 가공될 수 있으며, 가변링(350)의 외주면 중 타측은 상기 외부절연체(380)과 동일한 방향으로 테이퍼진 형상으로 가공될 수 있다. In addition, as another example of such a variable ring 350, the outer peripheral surface of the variable ring 350 may be implemented in a tapered form. At this time, one side of the outer peripheral surface of the variable ring 350 may be processed into a tapered shape in the same direction as the electrode body 310, the other side of the outer peripheral surface of the variable ring 350 in the same direction as the external insulator 380 It can be machined into a tapered shape.
이 경우 전극체(310)가 신체 조직의 내부로 들어가거나 또는 스텐트(150) 시술 후 빠져나올 때, 전극체(310) 또는 외부절연체(380)과 동일 방향으로 테이퍼져 있으므로, 신체 조직에 형성된 구멍에 걸리며 손상을 주는 문제를 방지할 수 있다. In this case, when the electrode body 310 enters the inside of the body tissue or exits after the stent 150, the electrode body 310 is tapered in the same direction as the electrode body 310 or the external insulator 380. It can prevent the problem of getting caught.
물론 전극체(310)와 밀착되어 전기적으로 연결되어 있으므로, 신체 조직에 구멍을 내는 직경 범위 조절도 가능하게 된다. 구체적인 설명은 상기와 같다.Of course, since it is in close contact with the electrode body 310 and electrically connected, it is possible to adjust the diameter range to puncture the body tissue. The detailed description is as described above.
본 발명의 실시예에서는 하나의 테이퍼 처리된 가변링(350)만을 제시하고 있으나, 가변링(350)상에 테이퍼 처리되는 형상은 보다 다양할 수 있으며, 본 발명으로부터 유추될 수 있는 범위내라면 다른 형상도 당연히 포함될 수 있다. In the exemplary embodiment of the present invention, only one tapered variable ring 350 is provided, but the shape of the tapered shape on the variable ring 350 may be more various, and other ranges may be inferred from the present invention. Shapes can of course also be included.
또한 본 발명의 실시예에서는 상기 가변링(350)의 외주면 일측은 상기 전극체(310)의 각도(Φ1)보다 작은 각도(Φ2)로 테이퍼지게 가공될 수 있으며, 상기 가변링(350)의 외주면 타측은 상기 외부절연체(380)보다 작은 각도로 테이퍼지게 가공될 수 있다. In addition, in the embodiment of the present invention, one side of the outer circumferential surface of the variable ring 350 may be tapered to an angle Φ2 smaller than the angle Φ1 of the electrode body 310, and the outer circumferential surface of the variable ring 350 The other side may be tapered at an angle smaller than that of the external insulator 380.
이러한 가공처리를 통해 전극체(310)에 가변링(350)이 장착되더라도, 전도되는 전류에 의한 열에 의해 신체조직에 소작하는 구멍의 크기는 보다 축소될 수 있다. 물론 단순히 소작 구멍의 크기를 축소하는 것뿐만 아니라, 반대로 확장할 수도 있다. 시술자는 테이퍼 각도를 가진 가변링(350)을 여러개로 구비할 수 있으며, 소작하고자 하는 신체 조직의 구멍 크기에 맞춰 가변링(350)을 바꿔 결합하여 사용하면 된다.Even if the variable ring 350 is mounted on the electrode body 310 through such processing, the size of the hole cauterized in the body tissue by heat caused by the conducted current can be further reduced. Of course, not only can you reduce the size of the cauterization hole, but you can also expand it. The operator may be provided with a plurality of variable ring 350 having a taper angle, it may be used by changing the variable ring 350 in accordance with the size of the hole of the body tissue to be cauterized.
한편, 도 19 및 도 20를 참고하면, 상기 가변링(350)의 내측 둘레와 상기 전극체(310)의 외측 둘레 사이의 이격을 방지하도록, 상기 결합부(330)의 적어도 어느 일측에는 밀착패드(360)가 배치될 수 있다. Meanwhile, referring to FIGS. 19 and 20, an adhesion pad may be provided on at least one side of the coupling part 330 to prevent a space between the inner circumference of the variable ring 350 and the outer circumference of the electrode body 310. 360 may be disposed.
본 발명의 실시예에서는 상기 결합부(330)의 양측에 상기 밀착패드(360)가 배치된다. 전체적으로 밀착패드(360)는 링 형상일 수 있으며, 전극체(310)의 외주면을 따라 억지끼움되어 배치될 수 있다. 이러한 밀착패드(360)는 상기 결합부(330)보다는 약간 외측으로 돌출된 유연성 있는 절연물질일 수 있다. In the embodiment of the present invention, the contact pads 360 are disposed at both sides of the coupling part 330. In general, the contact pads 360 may have a ring shape and may be disposed by being pressed along the outer circumferential surface of the electrode body 310. The adhesion pad 360 may be a flexible insulating material protruding slightly outward than the coupling portion 330.
이러한 밀착패드(360)의 배치로 인해, 시술자가 가변링(350)을 결합부(330)에 돌려 끼운 후에는 가변링(350)의 내주면과 전극체(310) 및 팁절연부재(320)의 외주면 사이에는 이격 부위가 없을 정도로 밀착되게 된다. 이는 전극체(310)가 신체 조직의 내부로 들어가거나 빠져나올 때, 가변링(350)과 전극체(310) 및 팁절연부재(320) 사이의 이격된 간격으로 피(blood), 조직(tissue) 등이 유입되어 끼이는 현상을 차단할 수 있게 된다.Due to the arrangement of the close contact pad 360, after the operator rotates the variable ring 350 to the coupling part 330, the inner circumferential surface of the variable ring 350 and the electrode body 310 and the tip insulating member 320 may be removed. There is no space between the outer circumferential surface is close enough. This is because when the electrode body 310 enters or exits the body tissue, blood and tissues are spaced at a spaced interval between the variable ring 350 and the electrode body 310 and the tip insulating member 320. ) Can be prevented from getting caught.
즉 가변링(350)의 제1 링부(351)과 전극체(310)는 모두 금속성 재질로 되어 있으므로, 기계적으로 완벽한 맞춤은 어려우며, 미세한 이격이 발생하게 된다. 이 이격을 상기 밀착패드(360)가 차단하게 되는 것이고, 이것은 인체 의료 기구의 정밀성에 도움을 준다.That is, since the first ring part 351 and the electrode body 310 of the variable ring 350 are both made of a metallic material, mechanical perfect fit is difficult and minute spacing occurs. The adhesion pad 360 is to block this separation, which helps in the precision of the human medical device.
물론 가변링(350)의 제2 링부(353)과 팁절연부재(320)간의 이격 간격은, 그 절연재질의 특성상 제1 링부(351)과 전극체(310)간의 이격 간격보다는 양호할 것이나, 역시 밀착패드(360)에 의해 간격 발생을 차단할 수 있게 된다.Of course, the spacing between the second ring portion 353 and the tip insulating member 320 of the variable ring 350 is better than the spacing between the first ring portion 351 and the electrode body 310 due to the nature of the insulating material, It is also possible to block the occurrence of the gap by the close contact pad 360.
한편, 도 21에는 본 발명에 따른 전극체(310)를 정면에서 바라본 형상이 게시되어 있다. On the other hand, the shape which looked at the electrode body 310 which concerns on this invention from the front side is shown by FIG.
그리고 도 22에는 전극체(310)의 다른 형상이 제시되는데, 상기 팁가이드홀(321)이 편심되어 배치되는 구조이다. 22 shows another shape of the electrode body 310, the tip guide hole 321 is disposed eccentrically.
이러한 편심된 팁가이드홀(321)이 가공된 전극체(310)는 일반적으로 사용되는 것은 아니나, 시술환경에 따라 사용될 수 있다. 가령 예를 들어, 혈관계에서 혈관이 여러개로 갈라지는 분기점에 본 발명인 스텐트 전달 시스템(100)이 삽입되었을 때, 원하는 방향의 혈관에 전극체(310)를 이동시키고 싶을 경우에는 편심되어 있는 팁가이드홀(311)을 그 혈관 방향으로 돌려 바라보도록 위치시키면, 가이드와이어(140)를 보다 쉽게 그 혈관 내부로 이동시킬 수 있게 된다. The electrode body 310 in which the eccentric tip guide holes 321 are processed is not generally used, but may be used according to a treatment environment. For example, when the stent delivery system 100 of the present invention is inserted into a branching point at which blood vessels are divided into several parts in the vascular system, an eccentric tip guide hole (when the electrode body 310 is moved to a blood vessel in a desired direction) is inserted. Positioning 311 in the direction of the vessel to look at it, it is possible to move the guidewire 140 more easily inside the vessel.
그리고, 본 발명에서는 상기 전기 소작 팁(300)은 도 23 내지 도 25에 도시된 바와 같이, 상기 전극체(310)의 외주면에 형성되는 소작돌기(370)를 더 포함하여 구성될 수 있다. 이러한 소작돌기(370)는 상기 전극체(310)의 외주면에 소정 간격을 두고 복수개가 배치될 수 있다. In addition, in the present invention, the electrical cauterization tip 300 may further include a cautery protrusion 370 formed on the outer circumferential surface of the electrode body 310 as illustrated in FIGS. 23 to 25. The cautery protrusions 370 may be arranged in plural on the outer circumferential surface of the electrode body 310 at predetermined intervals.
도 23에는 180도 간격으로 배치되는 2개의 소작돌기(370), 도 24에는 90도 간격으로 배치되는 4개의 소작돌기(370)가 각각 배치된 것을 확인할 수 있으며, 이는 신체 조직을 소작할 때 미리 소작 절개 방향을 안내하므로, 신체 조직 손상을 최소화하는 효과도 기대할 수 있다. 도 25에서와 같이, 상기 소작돌기(370)는 직선형이 아닌 나선형으로도 배치될 수 있다. In FIG. 23, two tenant protrusions 370 disposed at 180 degree intervals and four tenant protrusions 370 arranged at intervals of 90 degrees are disposed in FIG. 24. Since the cauterization direction is guided, the effect of minimizing damage to body tissues can also be expected. As shown in FIG. 25, the cautery protrusion 370 may be arranged in a spiral rather than a straight line.
이러한 소작돌기(370)가 소정 간격이 아니라 각각 다른 간격으로도 배치될 수 있고, 본 발명으로부터 유추될 수 있는 다른 형태도 본 발명의 실시예에 포함될 수 있다.The cavernous projections 370 may be arranged at different intervals instead of at predetermined intervals, and other forms that may be inferred from the present invention may be included in embodiments of the present invention.
또한, 도 26 내지 도 27를 참고하면, 본 발명의 실시예에서는 상기 가변링(350)은 서로 다른 두께를 가지도록 제공될 수 있다. 예를 들어 먼저 도 26를 참고하면, 신체 조직에 내는 소작 구멍이 타원 형상으로 요구될 때는 상기 가변링(350)의 일부 두께(D1)이 다른 부분의 두께(D2) 보다는 크게 형성된 가변링(350)을 장착하여 사용하는 것이다. In addition, referring to FIGS. 26 to 27, in the embodiment of the present invention, the variable ring 350 may be provided to have different thicknesses. For example, referring first to FIG. 26, when a cauterization hole for body tissue is required in an ellipse shape, the variable ring 350 having a part thickness D1 of the variable ring 350 larger than the thickness D2 of the other part is formed. ) To be used.
만약 소작하고자 하는 구멍이 어느 한 부분만 돌출되기를 원하다면, 도 27에 도시된 바와 같이, 가변링(350)의 어느 한 부분의 두께(D3)가 다른 부분의 두께(D4)보다 두껍게 형성된 가변링(350)을 장착하여 사용하는 것이다. If the hole to be cauterized wants to protrude only one portion, as shown in FIG. 27, the variable ring in which the thickness D3 of one portion of the variable ring 350 is thicker than the thickness D4 of the other portion, is shown. It is to use the 350.
이러한 가변링(350)의 형상은 도 26 및 도 27에서는 2가지만을 제시하였으나, 동일한 목적을 가지는 범위내에서 유추될 수 있는 다양한 두께로 형성된 가변링(350)이 포함될 수 있음은 자명할 것이다. Although the shape of the variable ring 350 is shown in FIG. 26 and FIG. 27, it will be apparent that the variable ring 350 having various thicknesses that can be inferred within the range having the same purpose may be included.
한편, 본 발명의 다른 예로는 도면으로 도시되지는 않았으나, 상기 복수의 소작돌기(370) 사이의 간격은 절연코팅될 수 있다. 이 경우 전극체(310)는 절연코팅되므로, 신체 조직을 소작하는 것은 소작돌기(370)만이 수행하게 되어 신체 조직의 소작 범위를 축소시킬 수 있다. 물론 도면으로 도시하지는 않았으나, 시술환경에 따라서는 가변링(350) 또한 절연코팅하는 것을 고려할 수 있을 것이다. On the other hand, although not shown in the drawings of another example of the present invention, the spacing between the plurality of cautery projections 370 may be an insulation coating. In this case, since the electrode body 310 is insulation coated, cauterizing the body tissue is performed only by the cautery protrusion 370, thereby reducing the cauterization range of the body tissue. Although not shown in the drawings, of course, depending on the treatment environment, the variable ring 350 may also be considered to insulated coating.
본 발명의 구조 및 다양한 실시예에 대한 설명은 상기와 같으며, 이하에서는 본 발명에 의해 스텐트 전달 과정을 살펴보도록 한다.Description of the structure and the various embodiments of the present invention is as described above, the following to look at the stent delivery process by the present invention.
도 28은 스텐트가 확장되는 상태를 나타낸 도면이고, 도 29 내지 도 34는 본 발명이 인체 조직의 내부로 스텐트를 전달하는 작동과정을 나타낸 도면이다. 작동상태에 대해 설명에 필요한 도면부호는 도 3 내지 도 도 16를 참고하도록 한다.FIG. 28 is a view illustrating a state in which the stent is expanded, and FIGS. 29 to 34 are views illustrating an operation process of delivering the stent into the human tissue. Reference numerals required for the description of the operation state refer to FIGS. 3 to 16.
먼저 도 29를 참고하면, 시술자는 스텐트(150)를 시술하고자 하는 신체 내부의 위치를 정확히 지정하고 스텐트(150)의 투입 경로를 안내하기 위해, 가이드 와이어(140)를 우선하여 삽입한다. 즉 도 29에서는 스텐트(150)를 시술하고자 하는 신체 조직의 부위(T1, T2)로 가이드 와이어(140)를 삽입하게 된다.First, referring to FIG. 29, the operator inserts the guide wire 140 in order to accurately specify a position inside the body to be operated on the stent 150 and to guide the input path of the stent 150. That is, in FIG. 29, the guide wire 140 is inserted into the portions T1 and T2 of the body tissue to be treated with the stent 150.
다음 가이드 와이어(140)가 신체 조직의 부위(T1, T2)에 위치하게 되고, 스텐트(150) 전달 방향이 설정되면, 시술자는 팁절연부재(320)의 팁가이드홀(321)에 가이드 와이어(140)의 단부가 끼워지도록 하며, 이에 따라 가이드 와이어(140)는 팁 가이드홀(321)로 유입되고, 제1 내부튜브(410)의 인너홀(411), 이동바(490)의 바인너홀(491) 및 제2 그립바디(481)에 형성된 제2 인너홀(482)을 관통하며 위치하게 된다.Next, when the guide wire 140 is positioned at the parts T1 and T2 of the body tissue, and the stent 150 is delivered, the operator may use the guide wire 321 in the tip guide hole 321 of the tip insulation member 320. The end of the 140 is fitted, so that the guide wire 140 is introduced into the tip guide hole 321, the inner hole 411 of the first inner tube 410, the binder hole of the moving bar 490 The second inner hole 482 formed at the 491 and the second grip body 481 may be positioned to penetrate the second inner hole 482.
이후에, 30에서와 같이 시술자는 스텐트 전달 시스템(100) 전체를 잡고 가이드와이어(140) 방향으로 밀어넣게 된다. 이에 따라 외부튜브(450) 및 전기 소작 팁(300)이 신체 조직의 내부(T1,T2)로 유입된다. Thereafter, as in 30, the operator grasps the entire stent delivery system 100 and pushes it toward the guidewire 140. Accordingly, the outer tube 450 and the electrical cauterization tip 300 are introduced into the interior (T1, T2) of the body tissue.
이때 커넥터부(200)가 외부 전류원(110)으로부터 전류를 공급받는데, 제1 전극선(123)이 외부 전류원(110)의 양극 단자에 연결되어(설명의 편의상 제1 전극선이 양극에 연결된 것으로 가정함) 전류가 유입되고, 제1 전극선(123)과 연결된 제1 전극체(313)이 양극을 띠게 된다.At this time, the connector unit 200 receives a current from the external current source 110, the first electrode line 123 is connected to the positive terminal of the external current source 110 (for convenience of description it is assumed that the first electrode line is connected to the positive electrode) The current flows in, and the first electrode body 313 connected to the first electrode line 123 has an anode.
그리고 제2 전극선(125)이 외부 전류원(110)의 음극 단자에 연결되고 (설명의 편의상 제2 전극선이 음극에 연결된 것으로 가정함), 제2 전극선(125)과 연결된 제2 전극체(315)이 음극을 띠게 된다.The second electrode line 125 is connected to the negative electrode terminal of the external current source 110 (assuming that the second electrode line is connected to the negative electrode for convenience of description), and the second electrode body 315 connected to the second electrode line 125. This cathode is taken.
이에 따라 전기 소작시 도 30에 게시된 확대도처럼, 제1 전극체(313)에서 흐르는 전류(E)는 신체 조직(T1)으로 유입되어 최단 거리로 제2 전극체(315)로 흐르게 된다. Accordingly, as shown in the enlarged view of FIG. 30 at the time of electric cauterization, the current E flowing in the first electrode body 313 flows into the body tissue T1 and flows to the second electrode body 315 at the shortest distance.
이 과정에서 전류(E)가 지나가는 경로에 있는 신체 조직의 밀착 부위(TB)에서는 가열반응에 의한 전기 소작 작용이 발생하며 천공이 일어나게 된다.In this process, in the close contact area (TB) of the body tissue in the path through which the current (E) passes, the electrical cauterization action by the heating reaction occurs and the perforation occurs.
이러한 전기 소작 작용은 다른 신체 조직(T2)에서도 동일하게 진행되며, 구멍 생성 완료 후 도 31에서와 같이 상기 외부튜브(450)는 신체 조직의 내부(T1,T2)로 안정적으로 투입될 수 있다. This electrocauterization proceeds in the same manner in other body tissues T2, and after completion of the hole creation, the outer tube 450 may be stably introduced into the interior T1 and T2 of the body tissues.
이후에 시술자는 제2 인너홀(482)의 후단부에 위치하는 와이어배출구(403)를 통해 가이드와이어(140)를 잡아 뽑아내어 신체 조직의 부위(T1, T2) 및 스텐트 전달 시스템(100)의 내부에서 가이드와이어(140)를 제거한다.Thereafter, the operator pulls out the guide wire 140 through the wire outlet 403 located at the rear end of the second inner hole 482, so that the parts T1 and T2 of the body tissue and the stent delivery system 100 are removed. Remove the guide wire 140 from the inside.
이제 스텐트(150)를 시술부위로 비교적 근접하여 위치시키면, 시술자는 제1 손잡이부(470)와 제2 손잡이부(480)를 잡고, 제1 손잡이부(470)를 제2 손잡이부(480)의 방향으로 당긴다. 이때 제1 손잡이부(470)는 외부튜브(450)와 연결되어 있고 제2 손잡이부(480)는 이동바(490)에 의해 제2 내부튜브(430)와 연결되어 있으므로, 제1 손잡이부(470)가 이동바(490)를 따라 이동하면서 외부튜브(450)가 후퇴를 하게 된다. Now, if the stent 150 is positioned relatively close to the surgical site, the operator grasps the first handle 470 and the second handle 480, and the first handle 470 holds the second handle 480. Pull in the direction of. At this time, since the first handle part 470 is connected to the outer tube 450 and the second handle part 480 is connected to the second inner tube 430 by the moving bar 490, the first handle part ( The outer tube 450 retreats while the 470 moves along the movement bar 490.
여기서 제2 내부튜브(430)의 단부와 제1 내부튜브(410)의 단부는 연결되어 있으므로, 외부튜브(450)가 후진됨에 따라 제자리에 있던 제1 내부튜브(410)가 외부튜브(450)의 밖으로 노출되게 된다. Here, since the end of the second inner tube 430 and the end of the first inner tube 410 are connected, the first inner tube 410 in place as the outer tube 450 is reversed is the outer tube 450. Will be exposed out of.
도 28 및 도 32를 참고하면, 제1 내부튜브(410)가 외부튜브(450)의 밖으로 노출됨에 따라 스텐트공간부(130)에 배치되었던 스텐트(150)가 신체 조직의 내부(T1,T2)로 노출되게 된다. 스텐트(150)는 자가 확장을 통해 펼쳐지게 되고, 신체 조직의 원하는 부위(T1,T2)에서 그 기능을 수행하게 된다. Referring to FIGS. 28 and 32, as the first inner tube 410 is exposed to the outside of the outer tube 450, the stent 150 disposed in the stent space portion 130 may have the inside of the body tissue T1 and T2. Will be exposed. The stent 150 is unfolded through self-expansion, and performs its function at desired areas T1 and T2 of body tissues.
도 29 내지 도 34에서는 신체 조직의 2개의 영역(T1,T2)간을 연결하는 용도로 스텐트(150)가 펼쳐진 상태가 도시되어 있으나, 본 발명은 수축되거나 막힌 혈관, 요도, 폐 등과 같은 순환계에서 이러한 혈관, 요도, 폐 등의 순환계 관의 확장 용도로도 사용될 수 있다. 그 밖에 스텐트(150)가 필요시 되는 다른 신체 조직에서 그에 적합한 용도로 사용될 수 있다. 29 to 34 illustrate an unfolded state of the stent 150 for connecting the two regions T1 and T2 of body tissues. However, the present invention is directed to a circulatory system such as a constricted or blocked blood vessel, urethra, lung, or the like. It can also be used to expand the circulatory system such as blood vessels, urethra, lungs. In addition, the stent 150 may be used for a suitable purpose in other body tissues as needed.
다시 도 32를 참고하면, 외부튜브(450)가 후진함에 따라, 스텐트(150)가 제2 내부튜브(430)의 단부에 배치된 사인블록(433)에 의해 상대적으로 밀려나게 된다. 즉 스텐트(150)의 일단부는 사인블록(433)에 의해 막혀 고정된 상태이고, 이때 외부튜브(450)가 후방향으로 이동하므로, 스텐트(150)의 타단부에서부터 외부튜브(450)의 외부로 개방되게 되는 것이다. 그리고 스텐트(150)는 신체 조직(T1,T2)의 내부에 위치하고 천천히 자가확장되게 된다.Referring back to FIG. 32, as the outer tube 450 moves backward, the stent 150 is relatively pushed by the sine block 433 disposed at the end of the second inner tube 430. That is, one end of the stent 150 is blocked and fixed by the sine block 433, and at this time, since the outer tube 450 is moved in the rearward direction, from the other end of the stent 150 to the outside of the outer tube 450. It will be open. The stent 150 is located inside the body tissues T1 and T2 and slowly expands itself.
여기서 시술자는 사인블록(433)의 위치 식별을 통해 현재 스텐트의 신체조직 내부에서의 배치 위치를 확인할 수 있다. 이를 위해 사인블록(433)은 시술자가 식별할 수 있는 색상으로 도색되어 있을 수 있다. Here, the operator can check the placement position of the current stent in the body tissue by identifying the position of the sign block 433. For this purpose, the sign block 433 may be painted in a color that can be identified by the operator.
이후 시술자는 도 33에서와 같이 일부 확장된 스텐트(150)를 약간 당기어 원하는 신체조직에 스텐트(150)를 정확히 위치시킨 후, 제1 손잡이부(470)를 이동바(490)를 따라 더 후퇴시켜, 스텐트(150) 전체가 완전히 자가확장되도록 한다. Thereafter, the operator slightly pulls the partially extended stent 150 as shown in FIG. 33 to accurately position the stent 150 in the desired body tissue, and then further retracts the first handle part 470 along the moving bar 490. By doing so, the entire stent 150 is fully self-expanding.
그리고 도 34에서와 같이 천천히 스텐트 전달 시스템(100)을 전부 잡아당겨 신체조직에서 빼게 되고, 스텐트 시술을 완료하게 된다. Then, as shown in FIG. 34, the stent delivery system 100 is slowly pulled out of the body tissue and the stent procedure is completed.
이상의 사항은 스텐트 전달 시스템의 특정한 실시예를 나타낸 것에 불과하다.The foregoing merely illustrates specific embodiments of the stent delivery system.
따라서 이하의 청구범위에 기재된 본 발명의 취지를 벗어나지 않는 한도내에서 본 발명이 다양한 형태로 치환, 변형될 수 있음을 당해 기술분야에서 통상의 지식을 가진 자는 용이하게 파악할 수 있다는 점을 밝혀 두고자 한다.Therefore, it will be apparent to those skilled in the art that the present invention may be substituted and modified in various forms without departing from the spirit of the present invention as set forth in the claims below. do.
